SPECIPICATIGN forming part of Letters Patent No. 392,896, dated November13, 1889.

Application filed July 20, 1888. Serial No. 280,535.

To aZZ whom it may concern.-

Be it known that I, GEORGE WARBURTON, a citizen of the United States,residing at N orristown, in the county of Montgomery and State ofPennsylvania, have invented certain new and useful Improvements inDevices for Operating IVindow Blinds, &c; and I do hereby declarethefollowing to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to improvements in window-shutter workers; and itconsists in the novel construction and arrangement of parts whereby theshutters can be opened and closed without raising the sash, all as willbe hereinafter fully explained and claimed.

The annexed drawings, to which reference is made, fully illustrate myinvention, in which- Figure 1 represents an inside view of a window,showing my improvements attached. Fig. 2 is a top or plan view. Fig. 3is a plan view of the device detached from the window. Fig. 4 is a sideview of the part B. Figs. 6, 7, and 8 are detail views of the drums OD.Fig. 5 is a plan view of my device in modified form.

The object of my device is to provide means for opening and closingwindow-shutters without raising the window-sash from the inside of theroom, as will be further described.

Referring by letter to the annexed draw ings, A designates thewindow-sill, at each end of which is provided a slot in which is seateddrums D and G, that are connected to one another by an endless band, (2,the drum 0 being arranged within the room and the drum D on the outsideof the window. These drums are provided with flanges which are groovedto receive the endless band. The flange in the drum 0 is cut away, as ata, to permit said band to pass within the circular space and beconnected to the postpivot a of said drum, which said band is connectedfirmly to the drum D bya pin, a Thus when one drum is revolved the otherrevolves simultaneously with it.

As the pair of drums on each side of the window are alike both inconstruction and (No model.)

operation, I will describe only one pair. The

drum 0 has an outwardly semicircular flange,

B, having a series of perforations, b, in which engages a pin, 0 on thefree end of a hand lever, O, that has a handle, 0, and a pivotedthumb-piece, 0 which when operated withdraws said pin 0 from aperforation in the flange B. This drum 0 consists of an upper portionand a lower portion. The upper portion has a central pivot pin or stud,a which has a T-shaped head, I), that passes through a perforation, If,in the lower plate, and is keyed thereto by a fastening-plate, b havinga slot, If, which engages the T-shaped head I) aforesaid.

It will be seen that when the drum 0 is turned the drum D simultaneouslyturns with it,through the medium of the endless band (1, thereby openingor closing the shutter, as the case may be, by means of the pin or lugon the plate e, secured to the under edge of said shutter, being pivotedto the drum D at d, thereby operating the shutters without raising thesash, and the shutter can be locked at any point, whether closed oropen, by the pin 0 entering one of the perforations in the flange orplate B.

In Fig. 5 of the drawings I have shown my device in a modifiedform,wherein instead of the grooves in the drum I use segments ofgearing upon the drums O D, having a horizontal shaft, K, connecting thetwo drums, said shaft having pinions 7t 7t secured upon each end, whichmesh with the segments upon the drums, the shaft being passed throughperforations in brackets k 70 secured to the window-sill, the segmentsand pinions communicating motion from one drum to the other, thusdispensing with the endless band.

What I claim as new, and desire to secure by Letters Patent, is-

1. The within described shutter -worker, consisting of the drum composedof the upper section having the grooved flange, thumbcatch 0 c andcentral T-shaped post, the key Z) therefor, the lower section having thevertical semicircular flange, and flange B, having perforations b, thedrum D, having the offset to engage the pivot-pin b on the casting onthe shutter, and the hand connecting these In testimony whereolI affixmy signature in drums, all arranged and operating as and for presence oftwo witnesses. the purpose set forth. t

2. The drums G and D, connected by the GEORGE XVARBURTON. 5 endlessband, the drum 0 provided with the semicircular perforated flangeadapted to reeeive the pin on the hand-lever, substantially asdescribed.
